To answer my own question, the solution was here:

http://wiki.ros.org/rosjava/Tutorials...

I ended up forking the rosjava/rosjava_mvn_repo. Ended up putting it here: https://github.com/WPIRoboticsProject...

Now I can use the dependencies I've created in my project. Once I get a full release published I'll make a pull request to merge it in with the master repo.

Problem

I've created two repos https://github.com/WPIRoboticsProject... and https://github.com/WPIRoboticsProject...

I would like to publish java artifacts that are created by the gripjava_messages project so that I can use them as a gradle dependency in my core (non ros built) application GRIP

Am I better off opening a PR to try to add the grip_msgs project to this repository or should I try to host them on my own.

Both routes I'd be really grateful for some guidance. I'm running against brick walls in my search across the internet on how to do this correctly.

Other details

I'm using a customized docker container to pull those two repos together into ROS on my system. (That all works on my end). I can get the messages to generate as expected. The files end up in the $ROS_MAVEN_DEPLOYMENT_REPOSITORY as I expect them to.

I was planning on doing the same thing with travis when I built the project.

I've also opened this as an issue here: https://github.com/rosjava/rosjava_mv...
